This is a pack of two black Background Triple Hooks from Impact. These hooks are used to hold up three rolls of background paper. When secured to your wall with the included mounting hardware, these hooks become a permanent installation to your studio. Your background paper can then be hung using either a simple optional cross bar or Impact's optional Varidrive units that come with expandable cores and chains. These hooks will hold 3 rolls of 9 feet x 12 yards of seamless paper.
